Method for manufacturing combustible heat source for smoking article and smoking article comprising combustible heat source

Abstract

The present disclosure provides a method for manufacturing a combustible heat source for a smoking article, the method comprising the steps of: mixing a carbon powder and an organic binder (S1); preparing a combustible heat source composition for a smoking article by adding an aqueous sugar solution after the step S1 (S2); adding oil to the composition (S3); and compressing the composition (S4). The present disclosure is characterized in that the composition solves the surface cracking phenomenon during combustion of the heat source by comprising an aqueous sugar solution, and a smoking article to which the combustible heat source composed of the composition is applied is excellent in ignition and combustibility.
